Question
The Sun's angular size is $0.5^{\circ},$ and its distance is $1.5 \times 10^{8} \mathrm{km}$ Use this information to calculate the Sun's diameter.
Step 1
Since 1 degree = π/180 radians, we have 0.5 degrees = 0.5 * (π/180) radians ≈ 0.00873 radians. Show more…

the sun's angular diameter is measured to be 5089 second . the distance D of the sun from the earth is 1.496 * 10^11 m . what is the diameter of the sun ?
Diameter of the Sun If the distance to the sun is approximately 93 million miles, and, from the earth, the sun subtends an angle of approximately $0.5^{\circ}$, estimate the diameter of the sun to the nearest 10,000 miles.
